Over 1 Million Working Cycles Life NBR Solenoid Valve Diaphragm
with 8 Mounting Hole Number
Electromagnetic pulse valve diaphragm is the main component of
bag-type filter ash removal system, which is mainly used in pump
valve, automobile industry, pneumatic components, gas equipment,
electronic industry, electrical equipment, pneumatic and hydraulic
industry and other industries.
The common material of pulse valve diaphragm is rubber. Rubber
diaphragm is mainly used in flow, pressure, differential, liquid
level, constant temperature volume thermal compensation valves,
regulating valves, automatic mechanical follow-up devices, switches
and counters. Its advantages are high reliability, good complexity,
long working life and low cost. Uniform elastic structure can be
used in all kinds of rubber. The rubber diaphragm has a long
service life and can be operated synchronously with other control
components to ensure the injection of pulse compressed air. Even
under extremely harsh working conditions, it can guarantee its
normal work and long service life.

Practical Applicantion Machine of Solenoid Valve Diaphragm
Operation of electromagnetic pulse valve diaphragm
The pulse valve diaphragm is the air switch of the electromagnetic
pulse valve. The pressure gas controlled in front of the diaphragm
lifts the diaphragm, opens the electromagnetic pulse valve channel
and sprays on it, the electrical signal disappears, and the spring
of the electromagnetic leader immediately resets the moving column
and closes the unloading hole. Electromagnetic pulse valve
diaphragm control gas pressure and diaphragm spring force after
close the channel, the electromagnetic pulse valve to stop the
resistance of injection on the diaphragm hole, when the guide head
moving column is raised, when gas pressure unloading,
electromagnetic pulse valve diaphragm have the effect of air
resistance, when unloading closed cavity, after pressure gas is
quickly to make the electromagnetic pulse valve diaphragm close the
channel, stop blowing.
Structure performance
It is composed of single or multiple layers coated on both sides,
and it is also made of rubber without fabric. Membrane pressure
method according to its shape. According to the requirements of the
use of different materials can be manufactured, different fabric
diaphragm. The properties of the butyronitrile rubber and
polysulfide rubber used for the film, the properties of the rubber
used for the canvas disc film (often called diaphragm) and the
properties of some silicone rubber, fluorine rubber and
chlorohydrin rubber film developed in recent years are described as
follows.
The operating temperature and pressure range of the diaphragm
itself depends on the rubber, fabric and structure. The diaphragm
can work at -50~100 c and 0.4~ 0.8mpa. Fluorine rubber and silicone
rubber diaphragm can work at -80~232 c. Chlorohydrin rubber
diaphragm can work under pressure of 0.4~ 0.8mpa, good air
tightness, aging resistance, life and engine overhaul life is
equal.
